On his knees now, Silas ran his hands across the stone floor. He saw no cracks or markings toindicate a movable tile, so he began rapping softly with his knuckles on the floor. Following thebrass line closer to the obelisk, he knocked on each tile adjacent to the brass line. Finally, one ofthem echoed strangely.

地砖下是空的！

There's a hollow area beneath the floor!

塞拉斯笑了起来，看来他杀的那几个人都说了实话。

Silas smiled. His victims had spoken the truth.

他站起身来，在圣殿里寻找可以用来撬开地砖的东西。

Standing, he searched the sanctuary for something with which to break the floor tile.

High above Silas, in the balcony, Sister Sandrine stifled a gasp. Her darkest fears had just beenconfirmed. This visitor was not who he seemed. The mysterious Opus Dei monk had come to Saint-Sulpice for another purpose.

为了一个秘密的目的。

A secret purpose.

有秘密的又何止你一人呢，她想。

You are not the only one with secrets, she thought.

桑德琳嬷嬷不仅是这所教堂的看守人，还是一名卫士。今晚，那古老的隐修会机制又开始运行了。陌生人来到方尖碑的基座边是教友们发出的信号。

Sister Sandrine Bieil was more than the keeper of this church. She was a sentry. And tonight, theancient wheels had been set in motion. The arrival of this stranger at the base of the obelisk was asignal from the brotherhood.
